Hello All!
I have a lot of virtual machines with KVM hypervizor. For VM's disks I use LVM Volumes. It's more suitable to install virtual machines direct to the LV-volumes without making partition tables inside the LV. In this case it is very simple to perform online-resizing and mount snapshots in host system to perform backups.
So, my question is:
Is it possible to install CentOS 6 without disk partitioning?
Not possible with grub1 (legacy grub). Grub1 doesn't support booting off LVM, so you'll have to have a separate /boot partition.
If grub2 were available in CentOS 6 (and it isn't - rumors are maybe in EL7) then it would be possible to have /boot reside on LVM. Some time ago I set up a system without a separate /boot partition on LVM with grub2 using Debian (I did the same with a Fedora system since).
I don't see an issue with having a separate statically sized /boot partition. 100MB for CentOS 5 and 512MB or so for CentOS 6. Besides, what is on /boot that really needs to be backed up? Probably not much of anything that's different from any other system.
